GIANNI BETTINI, OF NEW YORK, N. Y.

PHONOGRAPH.

SPECIFICATION forming part of Letters Patent No. 488,380, dated December20, 1892.

Application filed March 14, 1892.

To all whom it may concern.-

Be itknown that I, GIANNI BETTINI, a subject of the King of Italy, and aresident of New York, in the county and State of New York, have inventedcertain new and useful Im provements in Phonographs, of which thefollowing is a specification.

My invention will be fully understood by reference to the accompanyingdrawings, in which t Figure 1 represents a side elevational view of aphonograin cylinder, and a phonogram provided with my improvements-Fig.2 is a part cross sectional, part end elevational view showing a portionof the apparatus-Fig. 3 is an enlarged detailed sectional-view of thoseparts of the apparatus shown on the right hand in Fig. 2-Fig. 4 is anenlarged elevational view of the opposite sides of the regulating weightwith the words recording and reproducing situated on opposite facesthereof.

Referring now to the drawings in detail in all of which like letters ofreference represent like partsl3 B represent parts of the frame whichcarry the adjustable diaphragm supporting arm (E) secured at the upperend by a thumb nut (T) and at the lower end by a fork (K) standard (Q)and adjustment screw (1), the enlarged portion (R) of the support (E)constituting a ring in which the diaphragm is pivotally sustained in asupport (N) by pivots (P P).

M is a mouth piece adjustably sustained by two'pairs of nuts (F F) uponscrew rods (G) adapted to be screwed into the screw holes (T T) in thering (R), the mouth piece being supported entirely independent from thediaphragm, and the latter havinga spider (S) on its lower side to whichthe stylus is attached.

The apparatus as so far described is fully disclosed in my priorapplication above re ferred to, and the present invention embodies theadditional feature of a record producing stylus (to) and a reproducingstylus (3) both lying in the same plane and attached to a singlestandard (6), which, in turn, is secured to the spider (S). On the outerend of the pivot (P) which carries the diaphragm supporting ring (N) issecured, by a set screw (25), a short standard (H) in the upper end ofSerial No. 424,814. (No model.)

which is pivoted a rotatable standard (2%) held in place by a set screw(t) and provided at its upper end with a pivoted extension (111), screwthreaded at its free end to receive an adjustable weight (W), on oneside of which is printed, engraved, or otherwise prepared the wordrecording and on the opposite side the word reproducing.

The operation of the apparatus is as follows:Suppose the phonogramcylinder (0) upon the axis (A) to be revolving in the direction of thearrow, and the weight (W) in the position shown on the left in fulllines. Under this condition of affairs the record producing stylus (a)is held in contact with the surface of the cylinder and is caused tomake a record on producing sounds in the mouth piece (M), while therecord reproducing stylus (8) attached to the same spider (S) is heldoutof contact with the cylinder. After the record is thus produced andthe cylinder restored to its starting point in the usual way theoperator rotates the standard (m') through an angle of one hundred andeighty degrees carrying with it the weight (W) and pivoted extension(m). As soon as it is released, therefore, the weight (W) causes thediaphragm to be tilted upon the standards or pivots (P P) into theposition shown in dot- -ted lines, thereby placing the recordreproducing stylus (s) in contact with the cylinder and removing therecord producing stylus (a) so that when the cylinder is again set inmotion the record will be faithfully reproduced from the same diaphragm.

When the apparatus is in the position shown in full lines in Fig. 1, theword recording will be infull view of the operator, thus indicating tohim that the recording stylus (a) is in operative position. When,however, the weight (W) and arm are revolved into the other positionshown in dotted lines so that the reproducing stylus is in operativeposition the word reproducing will be in full view of the operator. Itwill be apparent therefore, that I provide a simple means of indicatingto the operator, whether or not the apparatus is in condition for pro-.ducing or reproducing a record, thus avoiding the possible mutilation ofa cylinder upon which a record has already been produced.

I am aware that it is not broadly new with me to utilize a singlediaphragm in connection with two independent styles, one of which isdesigned to make a record, and the other to reproduce it, as I know thata phonograph has heretofore been constructed in which two styles havebeen pivotally secured to a pivoted bar or rod, which, in turn, wassecured to a single diaphragm, and I make no claim hereinafter broadenough to include such a structure. I am not aware, however, that anyone has heretofore rigidly secured a record making and a recordreproducing stylus to a single diaphragm in such manner as to adapt itto act for producing or reproducing a record at will, and my claims inthis particular are of a generic nature. Nor am I aware that any one hasheretofore devised a pivoted diaphragm carrying two styles, one of whichis adapted to makearecord upon a phonogram surface, and the other toreproduce it in combination with indicating mechanism which serves thedouble function of an indicator and a means for holding the styles inoperative relation with the surface, and my claims are also generic inthis particular.

Having thus described my invention what I claim and desire to secure byLetters-Patent of the United States is:

1. Aphonograph havinga record producing stylus and an independent recordreproducing stylus, said styles being attached by a rigid support to thediaphragm or other resonant medium substantially as described.

2. In a phonograph a pairof styles secured by a rigid support to adiaphragm and located in the same plane whereby one may be utilized forproducing a record and the other for reproducing itsubstantially asdescribed 3. In a phonograph a pair of styles secured to a diaphragm bya spider, one style being adapted to produce a record and the other toreproduce itsubstantially as described 4:- In a phonograph a pivoteddiaphragm having a record producing stylus and asecond or recordreproducing stylus rigidly secured to itsubstantially as described '5.In a phonograph a pivoted diaphragm having a record producing stylus,anda second or record reproducing stylus rigidly secured to saiddiaphragm in combination with means for causing either stylus to bearupon the phonogram surfacesubstantially as described 6. In a phonograph,a loosely pivoted diaphragm having a pair of styles rigidly secured toit in combination with adjustable means for causing eitherstylus to actat will-as described 7. In a phonograph a loosely pivoted diaphragm; apair of styles rigidly secured to said diaphragm in combination withreversible adjustable means for utilizing either style at willasdescribed 8. In a phonograph a pair of styles located in a verticalplane and rigidly secured to the diaph ragmas described- 9. In aphonograph a pivoted diaphragm carrying a pair of styles in combinationwith a reversible weighted indicator adapted to indicate which style isin contact with the surface and to maintain it in that position untilreversed, substantially as described.

10. A phonograph having a pair of independent styles rigidlysecured to apivoted diaphragm and a reversible weighted lever adapted to causeeither style at will to bear upon the phonogram surface.
